How to start mongodb shell?

I am using MAC and I have successfully logged in to the server and started the server using the following command

./mongod

then it says

Thu Jul 14 01:50:41 db version v1.6.5, pdfile version 4.5
Thu Jul 14 01:50:41 git version: 0eb017e9b2828155a67c5612183337b89e12e291
Thu Jul 14 01:50:41 sys info: Linux domU-44-23-67-56-32-F5 2.6.21.7-2.fc8xen #1 SMP Fri Feb 15 12:39:36 EST 2008 i686 BOOST_LIB_VERSION=1_37
Thu Jul 14 01:50:41 [initandlisten] waiting for connections on port 27017
Thu Jul 14 01:50:41 [websvr] web admin interface listening on port 28017

and after that whatever I write, its just a text. Terminal is not accepting any command. Response says "waiting for connections on port 27017" . What should I do to get rid of this? I also tried command to start the Shell by the following commnad:

./mongo

but its also a text there. Please help.

mongo --shell

will open the shell interface.

Both the mongod (database server) and mongo (database client shell) programs are command line programs and each expects to be run in its own command line session. So, after starting the server (as you did with "./mongod") you should open a second command line session and run "./mongo" in it to give you a command line shell for talking to the server.
